natd: failed to write packet back

[Steve Camp]

Can someone tell me what the following message logged to /var/log/messages
means, and whether I ought to be concerned about it:

  Aug 29 13:41:29 server natd[180]: failed to write packet back (Permission denied)

natd is process 180:

  root     180  0.0  0.1   532  272  ??  Ss   Wed11AM   0:17.15 /sbin/natd -f /etc/natd.conf -n rl0

% sudo cat /etc/natd.conf
use_sockets yes
same_ports yes

% grep natd /etc/rc.conf
natd_enable="YES"
natd_interface="rl0"
natd_flags="-f /etc/natd.conf"

Thanks,
